6, 8, and 10 mm would be the equivalent of 1/4", 5/16", and 3/8" respectfully. I think you said 3/4 by mistake. That would be a bad day.... I've used those before when they came with some european products and was always curious who made them. Their holding power is quite astonishing! Good to see you, Mike!
